mLRS Documentation: OLED Display
February 15, 2026 ยท View on GitHub
mLRS allows for an OLED display to be connected to a Tx module (128x64, SSD1306 using I2C). When paired with a 5-way joystick (4 directions + select) this allows for one to update parameters and display link statistics. The OLED is particularly useful on radios that do not have a color screen and cannot utilize the color Lua script.
